APPLICANTS. 

A PATENT may be obtained by any person who 
has invented or discovered any new and useful 
art, machine, manufacture, or composition of 
matter, or any new and useful improvement 
thereof, not known or used by others in this 
country, and not patented or described in any 
printed publication in this or any foreign coun- 
try, before his invention or discovery thereof, 
and not in public use or on sale for more than 
tw^o years prior to his application, unless the 
same is proved to have been abandoned ; and 
by any person who, by his own industry, genius, 
efforts, and expense, has invented and produced 
any new and original design for a manufacture, 
bust, statue, alto-relievo, or bas-relief ; any new 
and original design for the printing of woolen, 
silk, cotton, or other fabrics ; any new and 
original impression, ornament, pattern, print, 
or picture to be printed, painted, cast, or other- 
wise placed on or worked into any article ot 
manufacture ; or any new, useful, and original 
shape or configuration of any article of manu- 

3 



facture, the same not having been known nor 
used by others before his invention or produc- 
tion thereof, nor patented nor described in any 
printed publication. 

If it appear that the inventor, at the time of 
rnaking his application, believed himself to be 
the first inventor or discoverer, a patent will 
not be refused on account of the invention or 
discovery, or any part thereof, having been 
known or used in any foreign country before 
his invention or discovery thereof, if it had not 
been before patented or described in any printed 
publication. 

Joint inventors are entitled to a joint patent ; 
neither can claim one separately. Independent 
inventors of distinct and independent improve- 
ments in the same machine cannot obtain a joint 
patent for their separate inventions ; nor does 
the fact that one furnishes the capital and an- 
other makes the invention entitle them to make 
application as joint inventors ; but in such case 
they may become joint patentees. 

The receipt of letters patent from a foreign 
government will not prevent the inventor from 
obtaining a patent in the United States unless 
the invention shall have been introduced into 



public use in the United States more than two 
years prior to the application. But every patent 
granted for an invention which has been previ- 
ously patented by the same inventor in a foreign 
country will be so limited as to expire at the 
same time with the foreign patent, or if there be 
more than one, at the same time with the one 
having the shortest unexpired term ; but in no 
case will it be in force more than seventeen years. 



All communications relating to American and Foreign 
Patents, Trade-marks, Copyrights, etc., should be ad- 
dressed to

AS TO THE NOVELTY OF AN 

INVENTION. 

An experience of more than sixteen years in 
the patent business, together with a continual 
perusal of the Patent Office pu»bIica*tions and 
familiarity with all branches of manufacture, 
enables me to form a reasonably correct idea as 
to the patentability of an invention by giving it 
an examination personally. This service I render 
to my clients gratis. It is, however, frequently 
advisable to have a special examination made at 
the Patent Office to ascertain whether an inven- 
tion is probably patentable. This entails a great 
deal of labor, to cover the cost of which I make a 
ch irge of $5. While this preliminary examination 
does not determine positively whether an inven- 
tion is patentable, it often determines that it is 
not patentable, by pointing out some prior pat- 
ent or invention of substantially the same charac- 
ter ; and where, as in such a case, the report is 
unfavorable, the entire expense of a patent ap- 
plication is saved. 



Persons who write for such information as is given 
gratis will please remember to enclose a stamp for reply.

COST OF SECURING A PATENT. 
Sixty dollars covers the entire expense of a 
patent for a simple invention. The fees are dis- 
tributed as follows : 

First government fee 1 15.00 

Agency fee 25.00 

Cost of the application . .$40.00 

Final government fee 20.00 

Total $60.00 

The government fees are the same in all cases, 
but it frequently happens that so much labor is 
involved in the spec-ification and drawing that 
the agency fee quoted above is insufficient. 

The applicant will be advised what the cost 
will be in any particular case. 



HOW TO PROCEED TO OBTAIN 
A PATENT. 
I St. Send a model, photograph, or sketch of the 
invention if a mechanical one, or a design. If 
it is a composition of matter, send samples of 
each ingredient, also a sample of the composi- 
tion. If it is a process, send sketches if they 
will assist in making the process clear. 



8 

2d. In any case send as full a description of 
the invention as possible, giving all its uses and 
describing the various modifications of which it 
is susceptible. 

3d. Remit $15 on account. The money should 
be sent by P. O. money order, by draft, or by 
express. Money sent in any other way is liable 
to be lost. 

On receipt of these I immediately prepare the 
drawing and specification, and mail the papers 
for signature, etc., at the same time calling for 
the agency fee. When the papers are returned 
to me, I forward them at once to the Patent 
Office, where they are filed. The applicant ^s 
notified of every important action of the examin- 
ers, and is consulted in regard to amendments 
whenever they are necessary. When the patent 
is allowed, the applicant is notified, and the final 
government fee ($20) is called for. This fee 
must be paid within six months from the date 
of allowance, and the applicant is advised to pay 
it as early as possible if there are no special 
reasons for delay. 

The patent issues in about three weeks after 
the payment of the final fee. 



PREPARATION OF THE CASE, 

The cases of my clients receive my constant 
personal attention from the mo«ment they are 
taken in hand to the last action of the Patent 
Office. I prepare the specification with great 
care, and draw the claims with a view to cover- 
ing all the inventor is entitled to. 

Since the recent decision relating to reissues, 
it has become a matter of the greatest import- 
ance to the inventor to have his application 
properly prepared, as it is now impossible to 
obtain reissues on the same conditions as for- 
merly, and it is possible only in rare cases to ob- 
tain a reissue at all. 

In order to realize from an invention, not only 
must the invention itself be valuable, but it 
must be protected by a good and valid patent. 
A poor patent does not protect the manufac- 
turer, and no capitalist will invest in an im- 
provement that is not well protected. 



All communications relating to Patents, Trade-marks, 
Copyrights, etc., should be addressed to 

Geo. M. Hopkins, 

Patent Attorney^ 
137 Temple Court, 3 to 9 Beekman Street, 
New York. 



10 

MODELS. 
Models are not required by the Patent Office 
except in complicated inventions where they are 
deemed necessary or useful to the examiner. 
This is determined after the application is filed, 
and the applicant will be notified if a model is 
required. 



CAVEATS. 

A CAVEAT, under the patent law, is a notice 
given to the office of the caveator's ciaim as m 
ventor, in order to prevent the grant of a patent 
to another for the same alleged invention upon 
an application filed during the life of the caveat 
without notice to the caveator. 

Any citizen of the United States who has 
made a new invention or discovery, and desires 
further time to mature the same, may file in 
the patent office a caveat setting forth the object 
and the distinguishing characteristics of the 
invention, and praying protection of his right 
until he shall have matured his invention. The 
caveat is filed in the confidential archives of the 
Patent Office and preserved in secrecy, and is 
operative for the term of one year from the filing 
thereof. 



11 

An alien has the same privilege, if he has re- 
sided in the United States one year next preced- 
ing the filing of his caveat, and has made oath 
of his intention to become a citizen. 

The caveat must comprise a specification, oath, 
and, when the nature of the case admits of it, a 
drawing, and, like the application, must be lim- 
ited to a single invention or improvement. 

A cav#at may be renewed from year to year. 

Cost of filing a caveat affording protection 
for one year : 

Government fee $10.00 

Agency fee 10.00 

Tota4 JS20.00 



DESIGNS. 



A PATENT for a design may be granted to any 
person, whether citizen or alien, upon payment 
of the duty required by law, and other due pro- 
ceedings had, as in 01 her cases of inventions or 
discoveries. 

Patents for designs are granted for the term 
of three and one-half years, or for seven years, 



12 

or for fourteen years, as the applicant may, in 
his application, elect. 

When the design can be sufficiently repre- 
sented by drawings or photographs, a model 
will not be required. 

Whenever a photograph or an engraving is 
employed to illustrate the design, the applicant 
will be required to furnish twelve copies of such 
photograph or engraving (not mounted), of a 
size not exceeding 7^ inches by 1 1. 

The cost of a design patent for ^^ years is— 



Government fee ... $10.00 

Agency fee i5-oo

Total ; $45.00

13 

TRADE-MARKS. 

Any person, firm, or corporation may register 
a trade-mark by complying with the rules of the 
Patent Office. It is immaterial whether the 
trade-mark has been long in use or not. Trade- 
marks continue in force for thirty years, and 
may be renewed for thirty years more. 

The entire cost of registering a trade-mark is 
$40 ; of this amount $25 is the government fee, 
and $15 is the agency fee. 

Any one desiring further particulars is re- 
quested to call on me or write. 



LABELS. 

The entire expense of registering a label or 
print to be used on merchandise is $16 (govern- 
ment fee $6, agency fee lio). On receipt of six 
copies of the label or print and sixteen dollars, 
I prepare the papers and file them in the Patent 
Office, and as soon thereafter as possible for- 
ward to the applicant the certificate of registra- 
tion. 

Copyrights for labels remain in force for 
twenty-eight years, and may be extended for 
fourteen years more. 



14 

COPYRIGHT. 

A BOOK, map, chart, dramatic or musical com- 
position, engraving, cut, print, photograph, or 
the description of a painting, drawing, chromo, 
statue, statuary, or model or design for a 
work of the fine arts may be copyrighted. 

To secure a valid copyright, the title or de- 
scription must be recorded in the Library of 
Congress before the publication of the work. 

Within ten days after publication of each book 
or other article, two complete copies of the best 
edition issued must be sent to the Librarian of 
Congress to perfect the copyright. 

Copyrights are granted for twenty-eight years, 
and may be renewed for fourteen years more if 
the renewal is filed within six months before the 
expiration of the first term. 

To secure a copyright send the title, and in 
case of a work of art send a brief description 
and remit $5, which covers all expenses. 



ASSIGNMENTS. 
An invention may be assigned before or after 
the application for a patent or after the issue of 
the patent. An inventor may assign the whole 



15 

or any part thereof, and he may authorize the 
ssLie of the patent to the assignee or assignees. 
The cost of drawing an assignment and re- 
:ording it at the Patent Office is $5. 



REJECTED CASES. 
An inventor should never despair on account 
of a rejection at the Patent Office. Many cases 
given up by inventors and persons inexperi- 
enced in practice before the Patent Office have 
been revived and prosecuted to a successful 
issue. I have given much attention to this class 
of work, and can get a patent if it is among the 
possibilities. 



COPIES OF PATENTS. 
Printed copies of the specification, together 
with the drawings of any patent granted since 
January i, 1866, furnished for 25 cents each, 
provided the name of the inventor and date or 
number of the patent is furnished. If only the 
name of the inventor or the name of the inven- 
tion can be furnished, 75 cents additional will 
be charged for looking the matter up. 



16 

THE FACULTY OF INVENTING. 

This faculty as popularly understood is pos- 
sessed to a greater or less degree by every mem- 
ber of the human family, and is constantly ac- 
tive in the daily routine of life. Inventing, as 
the dictionary has it, is '^ contriving that which 
did not before exist," but it cannot be claimed 
that man has creative power, nor can he do 
otherwise than use what already exists m the 
great storehouse of nature. The fundamental 
principles and the materials in which to em- 
body these principles are all there, and avail- 
able to one possessing sufficient acumen to see 
them. 

The obtuseness and blindness of men are never 
more fully realized than w^hen some inventor 
with more penetration than his fellows sees an 
opportunity for invention, invents, and acquires 
wealth by bringing into existence some simple 
contrivance that is immediately adopted and as- 
serts itself as a necessity, when everybody says, 
'' Why didn't some one think of that before ^ " 

It all seems easy enough and natural enougii 
after it is done, and it is a wonder why it was 
not done before. The trouble is just here — in- 
ventors, and many who might be inventors, 



17 

do not school themselves to systematic ob- 
servation. They should have eyes in all di- 
rections ; they should let no observed phenom- 
ena go uninvestigated ; they should revolve 
every subject so as to see its bearings on every- 
thing relating to it. No machine, no process, 
no tool, coming under the observation of the in- 
ventor should be allowed to pass without rais- 
ing such questions as these : Can this device be 
made to yield better results than it does now ? 
Can it be made to do its work quicker and 
cheaper than it does now^ ? Can its constx*'jc- 
tion be simplified or cheapened ? Can power 
be economized ? Can something else simpler 
and cheaper be devised for the same purpose? 
A real inventor never tires, and he not only 
scrutinizes the inventions of others, but treats 
his own in like manner. His object is to im- 
prove wherever an opportunity presents itself, 
and to secure to himself the benefits of such im- 
provements. 

It is a curious fact that although nature has 
shown from the foundation of the universe that 
molecules of water fliy from each other w^ith 
great force when subjected to heat, this force 
was not fully utilized until the days ["of Watt. 



18 

Nearly all of the great inventions of modern 
times have substantially the same history as that 
of the steam engine. The principles existed and 
so did the materials, but centuries were required 
to develop the inventions. 

A future of vast possibilities lies before the 
inventor of to-day, and with energy, perseverance, 
and a cultivated faculty of inventing, great prizes 
are within his reach. 



FOREIGN PATENTS. 
As a rule, foreign patents are equally as valu- 
able as American patents. 

Cost to apply for foreign patents : 

Canada . . $40.00 

England . . . . , 75«oo 

Germany 100.00 

Austria 100.00 

France ... 100.00 

Belgium 100.00 

Spain 100.00 

The cost of completing an English patent is 
$175 ; but it is probable that the entire cost of 



19 

an English patent will soon be brought down 
to about the same price as that of France and 
Germany. 

Forty dollars secures a patent in Canada for 
five years. It may be twice extended in terms 
of five years each at the cost of $25 for each 
term, or the patent may be taken at once for the 
full term of fifteen years, at the cost of $80. 

Send for special circular on foreign patents. 



THE VALUE OF PATENTS. 
Naturally the inventor is not so anxious 
about how much his invention will advance civ- 
ilization, or build up the nation, or administer 
to the wants and pleasures of mankind gener 
ally, as he is about how much it will net him in 
dollars and cents ; but he must not forget that 
in proportion to the actual usefulness of an in- 
vention, and its adaptability to some great want 
felt by every one, is the chance of profit. And 
it matters little whether the inventor intends 
himself to deal with the public, or to deal with 
a man, or set of men, who arc afterward to deal 
with the public — tlie conditions are the same. 



20 

Now let the inventor consider himself a disin- 
terested party, a referee if you please. Let him 
look upon his own invention as that of another. 
If he honestly concludes that it would be desir- 
able to himself and others, then he should have 
great confidence in the merit of his invention, 
and he should be able to make a fair estimate of 
the actual value of it. Having made such an 
estimate, he should allow for all contingencies 
and then deduct what would be to the buyer a 
fair margin of profit ; then he will have a basis 
on which to proceed in fixing the price of the 
patent. 

The inventor who has confidence in his own 
work is, generally speaking, the best man to 
transact the business of selling his patent. His 
best plan of procedure is to appeal personally 
to capitalists. It is usually easy enough to find 
a m.an who is willing to furnish the capital 
necessary to carry on business under a good 
patent for a good thing. Often capitalists pre- 
fer to purchase outright. It is common to sell 
patents to a set of men who organize a stock 
company to work under it. A large proportion 
of stock companies are based on patents. 

I do not engage in the purchase or sale of 



31 

patents, but, when desired, willingly give advice 
to my clients in regard to the sale or placing 
of their patents. 



OPINIONS. 

Manufacturers and capitalists desiring to 
invest in patents, and honest inventors who de- 
sire to dispose of their patents, should have a 
careful investigation made as to the status of 
the patent in question. This involves a great 
deal of labor, and some expense, depending of 
course on the number of patents in the class or 
classes to be examined, also upon the state of 
the art to which the invention is related. The 
price for making such investigations is variable, 
but an estimate will be furnished in any particu- 
lar case on application. 

A reliable investigation of this kind gives as- 
surance to all parties interested, and is invalu- 
able to all concerned. 



Any one receiving an extra copy of this book, 
will do the author a favor by giving it to some 
one interested in inventions. 



23 

FURTHER INFORMATION. 
The author of this pamphlet is cognizant of 
the fact that hundreds of questions that will occur 
to the inventor's mind, relati^^e to securing pat- 
ents, and other matters connected wi'-h inven- 
tions, are not answered in these pages. Indeed, 
it would be a difficult task to gather together in 
a volume of any size answers to all the queries 
put by inventors ; but the writer holds himself 
in readiness to reply to any questions that maybe 
made m person or by letter, and he cordially 
invites any desiring personal interviews or ad 
vice by letter to call or to write. 



Persons who write for such information as is given 
gratis will please remember to enclose a stamp for reply.

A GOLD MINE. 

It is the precious nugget in one form or other 
that all men are striving for. Some get of pre- 
cious metals ^' only a trace," as the assayer says. 
Some get the dust and others the nugget. The 
nugget is what is wanted. Some cross the con- 
tinent for it, others plough, sow, and reap for it, 
others hammer and bore and turn and file for it, 
still others wear away life in some profession 
for it, and all are impatient, hurrying hither and 
thither in hopes of reaching it quickly. There is 
a charm about wresting treasures directly from 
Mother Earth, but mining must of necessity be 
carried on where the treasures are, and to reach 
them the comforts of home and society must be 
left behind, and that without the certainty of 
success. 

With the inventor, his head is his gold mine. 
There he may search for treasures which may 
eventually be turned into gold. This mine can 
be worked while the miner enjoys the comforts 
of home and friends. Mining of this sort may 
be carried on in connection with manufacturing, 
commercial, or professional pursuits without 
interfering with them in the least. 



24 

So long as inventions can be turned into gold, 
the inventor's head is of greater value than a 
gold mine. 



CELERITY IN PATENT BUSINESS. 

The time was when it was thought by invent- 
ors that the process of patenting an invention 
might be hastened by bringing influence of one 
kind or another to bear at the Patent Office. 
Whatever foundation this supposition may have 
had, it is now well understood that a patent can- 
not be hurried through the Patent Office out of 
its regular course. The only way to save time 
in securing patents is to intrust the business to 
an attorney, who will prepare the application 
and file it at the Patent Office promptly, and 
who will vigorously follow up every action of 
the examiner and prosecute the case to a final 
issue, without unnecessary pauses. The Patent 
Office, while it is sometimes overburdened with 
business, is usually very prompt, acting on cases 
in from four to six weeks from the date of 
filing.

KEEP A RECORD OF YOUR 

INVENTION. 
The value of an accurate record of an inven- 
tion throughout its entire history cannot bt 
over-estimated. It is often of great value, even 
after a patent is granted. It fixes the date of 
invention, shows whether the inventor has exer- 
cised due diligence in perfecting his invention, 
and is an unimpeachable witness in cases of in- 
terference or any other litigation that may arise. 
Besides this, it enables the inventor to convey to 
his attorney a more perfect idea of his inven- 
tion, and what he desires to cover in his specifi- 
cation and claims. This record may be placed 
temporarily in the hands of the attorney to en- 
able him to prepare the case, and then it should 
be returned intact to the inventor. Of course 
the inventor should be careful . to select an at- 
torney known to be reliable. The inventor may, 
if he choose, retain the record in his own pos- 
session and send a copy of it to his attorney.

This engraving rather imperfectly represents one of the finest 
business buildings in New York. It is ten stories high, 
thoroughly fire proof, and a model of convenience. An im- 
mense court extends from the first floor to the glass dome 
above, and all of the offices are lighted from within as well as 
from wjthout. In this edifice, within almost a stone's throw of 
the New York Post Office, the City Hall, the Sun, Tribune, 
Times, World, Mail, Herald, and Post newspaper offices, are 
situated my offices.
